27-Year-Old Brendan Palmaccio Arrested For Threatening ADL CEO Jonathan Greenblatt On Twitter

BOCA RATON, FL (Boca Post) (Copyright © 2023) — A Boca Raton man was arrested and charged with written threats to kill after threatening Jonathan Greenblatt, CEO of the Anti Defamation League on social media.

27-year-old Brendan Palmaccio of Boca Raton was arrested and charged with written threats to kill or do bodily harm, according to court records. Boca Raton Police say that on August 1st, 2023, they were contacted by the Anti-Defamation League about a threat made on social media on 7/31. Several director-level people from the ADL told detectives that the were investigating a violent threat made on social media network Twitter, now known as ‘X’.

The content in question was a response to a re-tweet made by the CEO of the Anti-Defamation League, Jonathan Greenblatt (@JGreenblattADL), seen below:

According to detectives, Palmaccio responded to the above post, saying “You should go <expletive> your self you nazi <expletive> never forget 9/11 and <expletive> your deception … I wish you would <expletive> you you supremacists killed my family I’ll <expletive> murder you”

Palmaccio’s reply to Greenblatt’s re-tweet prompted an internal investigation which ultimately ended with the ADL contacting BRPD about the threatening comment.

Detectives starting looking at Palmaccio’s Twitter/X, calling him a “truth-seeker” while noting the existence of Jewish extremism content and tweets about “false flag” events. Palmaccio makes it very well known on his Twitter/X profile, @Bdubz4444, that his uncle died in 9/11.

Detectives eventually made contact with Palmaccio who agreed to speak with them about the investigation. Detectives say that Palmaccio made his Twitter account private prior to showing up for the interview.

Palmaccio stated he lost his uncle on September 11, 2001 and did not feel the media was telling the full story regarding the attacks. Palmaccio reportedly told Police that Muslims were good people and while he was not anti-Jewish, he was not in support of the ADL.

Palmaccio admitted to writing the threatening comment and said he since deleted it because he realized it was not a good idea.

BRPD arrested Brendan Palmaccio for violation of 836.10 Written Threats to Kill.

Palmaccio has not shared anything on X since his release from Jail on August 3rd, 2023.
